Creating pH-sensitive self-healing concrete using sludge waste for sewers. In Australia, our 117,000 km of concrete sewer pipes are currently internally corroding at a depth rate of 1-3 mm per annum. The repair of deteriorated concrete is costly and often short-lived. Based on an advanced composite technology, this project will develop a pH-sensitive self-healing concrete that can repair itself without human intervention at the early stage of corrosion.

In Australia, our 117,000 km of concrete sewer pipes are currently internally corroding at a depth rate of 1-3 mm per annum. The repair of deteriorated concrete is costly and often short-lived. Based on an advanced composite technology, this project will develop a pH-sensitive self-healing concrete that can repair itself without human intervention at the early stage of corrosion. Sludge waste from drinking water treatment will be utilised as a healing agent to mitigate the corrosion. Combined experiments and molecular dynamics simulation will uncover all aspects of the healing process to enable the practical application of this technology. The findings will extend the lifetime of concrete structures and promote a circular economy.Read moreRead less

Summary
Novel minerals and mix design in low embodied carbon concrete products . Research and development in materials and mix design for concrete building products will target utilisation of abundant and low cost mineral materials including natural clay, hard rock quarry fines and unclassified fly ash resources. New mix design and preparation methods are targeting improved strength and production efficiency with reduced Portland cement and embodied carbon.

Research and development in materials and mix design for concrete building products will target utilisation of abundant and low cost mineral materials including natural clay, hard rock quarry fines and unclassified fly ash resources. New mix design and preparation methods are targeting improved strength and production efficiency with reduced Portland cement and embodied carbon. This technology will be used in the manufacture of concrete blocks, roof tiles and brick and block mortar products currently manufactured by Brickworks. Outcomes are efficient and sustainable full scale manufacture of higher value, low embodied carbon, lightweight, large format and/or high durability products that are not currently available to the Australian market.Read moreRead less
